Be it known that we, CHARLES F. BERN- HARD and HARRY J. BERNH-ARD, citizens of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Lubrication Systems for Internal-Combustion Engines, of which the following is a specification.

ur object is to improve the set-u details of construction of an oil in and icator lubritratlng an engine combined W1th.a fly-wheel lubricating apparatus is positioned.

Fig. 2 is a View in section and elevation as seen on the line 2-2 of Fig. 1 illustrating the rotating magnets of the m agneto and relation thereto. Fig. 3 is an enlarged view illustrating the sight feed member of the device and particularly disclosing in detail the oil intake stem.

Fig. 4 is an enlarged fragn'ientary perspective showing the point at which the oil is taken from the magneto fly wheel.

teferring more particularly to the drawings, 10 indicates an internal combustion engine of the Ford type having a crank case 11 in which a crank shaft 12 rotates. Secured to the rear end of the crank shaft is a fly-wheel 13 upon the forward face of which are fixed a series of horse-shoe magnets 14 arranged radially and with their opened'ends extending outwardly. fly-wheel is inclosed I formed as a continuation of the crank case 11, and into which oil may flow from the crank case as it circulates.

e apparatus with which the above result is obtained consists of an oil intake stem 16 which is externally threaded and extends through a contact plug 18 the fixed magneto at an angle thereto.

through the engine casing directly in line with the peripheries of the horse-shoe magnets 14, this being the largest periphery of the fly wheel, and the magnets serving as blades to pick up the oil from the extreme bottom of t e case. This angle has been determined by the action of the oil as it is thrown from he magnets 14 so that the maximum force Will be obtained from this throwing action and Wlll deliver the oil to the intake opening 20 of the stem 16. This rectly strike the stem, as has been previously set forth, and thatit will not be necessarv to fill the crank case excessively in order to insure that a suflicient quantity of oil will be circulated.

In operation, the apparatus is applied to the engine as has previously been descrlbed. lVhen the engine is started, the crank and its fly-wheel will rotate in the direction of the arrow aas indicated in Fig. 2. This will cause the fly-wheel and the magpass through the'body of oil in of the fiy-wheel housing. This oil will be'caught between the .bars of the magnets and will be carried upwardly to be thrown off at a tangent to the path of travel of the ends of the magnets. This force will elevate the oil through the stem 16 and-the tube 22. Here it Will bubble sight feed and will led away by the inclined circulating tube 24. This will insure that the oil Will be continuously delivered ftothe the tube at, tion of oil will take vertically from the case and that the circu-' lating tube 24 extends downwardly and connects with the forward end of the case, a siphonic action is produced which will insure that the oil delivered to the stem 16 will be drawn upwardly through the tube 22 and will gravitate downwardly through thus insuring that the circulaplace without requiring the oil to be thrown into the opening 0 the stem with great force or when the engine is rotating at a high rate of speed.

It will thus be seen that the apparatus here disclosed, while simple in its construction, easily installed, and inexpensive as to manufacturing cost, provides that the oil within an engine crank case will be positively and continuously circulated in a desirable manner and without the use of special pumping mechanism.

\Vhile we have shown the preferred constructionbf our lubrication system for internal combustion engines as now known to us, it will be understood that various changes in the combination, construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of our invention as claimed.

We claim:

1. In a lubricating system for internal combustion engines wherein an engine is provided with a horizontal crank shaft at one end of which a fly-wheel is positioned havingradially disposed magneto magnetssecured to one of its side faces, said flywheel and crank shaft being inclosed within a housing partially filled with oil, the combination with said engine, of an oil receiving stem disposed through the side of the housing in alinement with the axial path of travel of the magnets and spaced therefrom, and a circulating pipe connected with said stem to convey the oil thrown by the magnets to an indicator and then to the forward end of said housing.

2. In a lubricating system for internal combustion engines of the class described, a tubular stem extending through the side of the fly-wheel housing of said engine and adapted to present an oil inlet opening to the oil thrown by centrifugal force from the radially disposed magnets uponthe face of the fly-wheel of said engine and to stand in aXial alinement therewith and spaced from'said magnets, an elevating tube in connection with said stem and through which the oil will be forced by the motion of said magnets, a sight feed through which the oil will pass, and a circulating nection with said sight feed to convey the oil to the forward end of the engine crank case.

3. A lubricating system for engines, comprising an oil receiving stem formed with an opening it its side in communication with a longitudinal bore leading to the opposite end of the stem, said stem being positioned through the fly-wheel and magneto case of said engine and in direct alinement with magnets upon the fly wheel, said oil receivin stem being spaced from said magnets an disposed through the side of the case to stand within the path of travel of oil thrown upwardly by the centrifugal force of said moving magnets, a sight feed with which said stem communicates, and a circulating pipe conveying the oil from the sight feed to the forward end of the engine where it is caused to pour over the timing gears and to thereafter circulate through the engine crank case.

In testimony whereof we have signed our names to this specification.
